Age of Conan makes its debut at the top of the US sales charts, beating out Blizzard's mighty World of Warcraft and EA's best selling The Sims series. The recently released MMORPG is also dominating European sales charts as well. Funcom's game is so popular that even its collector's edition nabs the 3rd place spot. Unfortunately this wasn't a good week for Sins of a Solar Empire which is knocked out of the top 10 since debuting in February.
